POTD Kelly Johnson, 2B

San-Man answered our Q's on Kelly Johnson, which got Eye-Gor to noodling around in the cave...

KJ's actually a pretty clear template from a sabermetric standpoint.  He got off track by (1) cutting down his swing (a lot) to make contact, and (2) expanding his strike zone (a lot) to not make contact.

Could a great batting coach fix him?  Well, you be da judge...

.

=== What Time Is the Game Over, Dept. ===

KJ's contact rate on swings in the zone went wayyyyyy up in 2009 ... Johnson made contact on a preposterous (for him) 94% of all swings, when the ball was inside the strike zone.

94% - KJ

79% - Dunn

78% - Howard

77% - Cust

75% - Branyan

Raul Ibanez was at 82%, Adam Jones at 83%, Jason Bay at 80%, Mike Cameron at 82% ... contact rate in the strike zone essentially sorts ML hitters by who is hitting for power (or trying to). 

Go to fangraphs, batters, plate discipline, sort by Z-Contact%, and you'll see the names line up beautifully in terms of how hard they're swinging.  (You'll also get a laugh out of Albert Pujols' stats.)

Other guys in Kelly Johnson's sky-high Z-Contact% range ... Christian Guzman, Jimmy Rollins, David DeJesus, Rafael Furcal, Chone Figgins.  You don't make contact with everything by putting your backside into it, kiddies.  You make contact with everything by arm-swinging.

.

=== Dumb Luck Dept. ===

Just the same, a pepper swing shouldn't produce the .240'ish BABIP that KJ ran.  That's getting into pitcher-at-the-plate BABIP.

.

=== Not the Best Plate Strategy, Keed ===

What is really interesting is that while KJ cut down his swing to make more contact, he also wayyyyyy expanded his strike zone -- swinging at far more pitches outside the zone.  

Here is a fine article by Brian Joura on it.  KJ swung at 18% of O-Zone's in 200 ... but 24-25% the last two years.  Yowch.

So what happens if you cut down your swing to be sure you make contact, and then start swinging at pitchers' pitches?   Well, you're going to roll over a lot of grounders to the shortstop and second baseman.  

KJ doesn't have the speed to slap the ball around.  He's going to run a lousy BABIP when he's arm-swinging at pitchers' pitches.

.............

The fact that KJ felt the need to cut down his swing suggests that he felt beaten by ML pitchers in 2008-09 ... and the fact that he stopped recognizing strikes suggests that he got all messed up inside his head.

KJ looks like a pretty serious reclamation project to me:  he's got to get back to contracting his zone, waiting for his pitch, and hitting the ball hard ... but his own opinion is that he's not capable of doing that.

It would be a masterly job of coaching that recovered him.

.

=== Opportunity Fire for the Right Sargeant ===

Kelly Johnson, when right, has been an Orlando Hudson comp offensively -- solid AVG, 60 walks, good gap power, "meh" defensively as Sandy put it.

Right now, he's (evidently) available cheap.  He's either a free agent after Dec. 12 or available (undoubtedly) for a grade B prospect prior.  At $3M or so, you supposedly save $5M a season (??) off Orlando Hudson.  That's more talent someplace else on your roster.

...........

The decision would stand or fall with some coach being V-E-R-Y confident that KJ could get back to his get-your-pitch-and-hit-it-hard game.  Whether the M's coaches think that, who knows.

The ideal diagnosis would be, KJ (1) opened up his strike zone, swinging at sucker pitches, and THEN (2) cut down his swing in self-defense, following the lousy results.  If so, then simply getting him to cut down the strike zone, could naturally restore his aggressiveness, right?

.........

Me?  I'll believe it when I see it.  If KJ doesn't think he can hit, why should I think so?  That's not a swipe; it's an analysis.  KJ's opinion on his own ability is very relevant.

But the M's brain trust is super-confident about reclamation projects, so, eyes slideways I guess.

Cheers,

Dr D

mojicianPlus, the starter conversion for Wilhelmson is experimental. Bartender is a temperamental pitcher and he is flourishing in his current roll.8 min 46 sec ago
mojicianYeah. I guess I've taken the Drayer point of view, that the difference between Erasmo/Wilhelmson and Lackey isn't going to make the team very much better. Erasmo/Wilhelmson 2014: 117.2 IP, 3.37 ERA. Lackey 2014, 137.1 IP, 3.60 ERA. Now, I know we aren't giving up Wilhelmson, but if we had another trustworthy starter, he would get a lot less innings. He already has 57.2 for the year, which is as much as you normally get out of a reliever for the whole year. His rubber arm is an asset, and the Erasmo five and dive coupled with the Wilhelmson mop up job has been doing very well so far.11 min 42 sec ago
benihanaWhile I have a fair amount of sports-hate for John Lackey, he's realistically probably a better bet than Young, Walker, and Elias down the stretch... hmmm...still, nope.13 min 33 sec ago
benihanaI rank our starters down the stretch as 1) Felix 2) Iwakuma 3) Paxton 4) Young 5) Walker 6) Elias (innings limit soon) 7) Ramirez 8) Wilhelmson... so can you trade Erasmo, sure! Should you trade him for Lackey? I wouldn't. Don't see Lackey as being better than our top 5. If we move Walker for a bat? Then, yeah, maybe... hmm.... nope, still can't stand John Lackey, don't want him in an M's uniform.22 min 28 sec ago
SABR Mattwe have another #6 starter though ,moj...Wilhelmson.28 min 31 sec ago
mojicianI consider the Number 6 starter, Erasmo, to be part of the big league club. If you get rid of your number 6 starter, then you won't have a good number 6 starter when you need him, which is early and often.44 min 57 sec ago
GLSNo on Erasmo and Franklin for Lackey. I'd rather save my bullets.56 min 58 sec ago
SABR Mattanother option to consider...would you give up Erasmo Ramirez and Nick Franklin for John Lackey?1 hour 40 min ago
SABR MattI'd give up Franklin plus another big guy who was not close to MLB ready (Sanchez/Pike level) plus a reliever for Lester...I would NOT give up Franklin and Peterson...heck I wouldn't give up Peterson.1 hour 41 min ago
SpectatorMy question: would you give up Franklin + another top guy for two months of Lester?1 hour 46 min ago
Spectatorrick: Walker + for Tulo for sure. Or Stanton. Otherwise I don't think so (among guys plausibly in the market).1 hour 49 min ago
mojicianWill Myers? He's just coming back from a broken wrist.1 hour 50 min ago
SABR MattKiermaier is not talented enough to keep up his current hot streak, I don't think...some players land with a splash until the league adjusts. That said...I would probably part with Walker for Kemp if they threw in a lot of salary, and I would definitely part with Walker for a guy like Jennings and obviously for Stanton (who I don't think is available at all)..beyond that...Troy Tulowitzki? If he weren't hurt, I mean? Maybe the Cubs would be willing to part with Baez and something else pretty to get Walker? eh...don't think I'd do that...it gets very...very tricky.1 hour 55 min ago
rick82A question I posed to Matt last night, but I would be interested in hearing from any or all: are there any bats out there, within reason and with a possibility of being available, that you would trade Walker for. I think we all would trade him for Stanton, and be ready to sweeten that offer. But are there any reasonable one for one offers you think would seriously be entertained by the other club that you would do? Me? I might seriously consider Walker for Jennings. And while we're at it, where on earth did Kiermaier come from???2 hours 33 min ago
SABR MattPaxton will almost certainly be back on Saturday...and to show you what I think of him, before it was even certain that he would come back, I jammed him right into my starting line-up in fantasy for this week. :)4 hours 15 min ago
phxterryFrom the "Glass Half - Empty Dept.": Last night LoDog kept up the M's continuous string of making an out on the base paths every game. From the "Glass Half-Full Dept.": It wasn't Fat Ichiro , infamous base clogger, who ran into the out because he didn't get on base in 5 PA's. So far he is 1-15 as a Mariner, which is very un-Ichiro like.4 hours 28 min ago
rick82I hope Hart figures it out and plays some right field here and there. I like to pretend it's Jay Buhner out there.4 hours 40 min ago
rick82Wow, Morales is struggling. This is bad. I don't remember so many K's in a single game, against inferior opponents, no less.4 hours 43 min ago
MtGrizzlyDrayer: • LHP James Paxton is with the team and will throw a bullpen session Wednesday. While a Saturday starter has yet to be named, it most likely will be Paxton if the bullpen session goes well.6 hours 37 min ago
IcebreakerXStill need to catch up, but if the Kemp-as-backup rumors are still around, I wonder if Plan A is actually Tulo?7 hours 50 min ago
